50% of the weight of the Flora

Relatively easy to extract from

Organic Municipal Solid Waste (MSW)

Paper

Wood chips

Cellulose agricultural wastes

Why Glucose ?

Glucose is the first stable product in photo-synthesis

Glucose is the building block in all the Saccharides:

Fructose, Maltose, Lactose,

Starch,

Cellulose.
